I translate some bases shaders to be able to work in Blend4web (B4W). Unfortunately there is a problem with the classic perlin noise witch seems to have too much uniforms, but anyway it was badly done. There is no textures, only nodes. Works fine on 2.79 with Blend4web addon. Works on Cycle by replacing the output node. Works on Blender Internal. You can make them work on 2.9 by replacing the geometry by a texture coordinate node.
